<span>The question is which microscope is often use to view metal. The answer is scanning tunneling microscope. It is a high resolution microscope which uses neither light nor electron beam but it has very fine tip which has the ability to reveal the atomic and molecular details of metals. It was developed in 1981 by Gerd Binnig and Heinrich Rohrer.</span>
A scanning tunneling microscope is an instrument for imaging surfaces at the atomic level. Its expansion in 1981 introduced its inventors, Gerd Binnig and Heinrich Rohrer, the Nobel Prize in Physics in 1986. The scanning tunneling microscope (STM) is a type of electron microscope that shows three-dimensional images of a sample. In the STM, the structure of a surface is considered using a graver that scans the surface at a set distance from it. A remarkably fine conducting probe is held near to the sample.
Perder un testículo usualmente no tiene ningún efecto en la capacidad de un hombre de lograr una erección y tener sexo. No obstante, si se extirpan ambos testículos, no se pueden producir espermatozoides y el hombre queda estéril.
